PUMP-"BASE.

To all whom it may mncerm:

residing at Trenton, in the county of Mercer, State of New Jersey, have"inventedcertain new and useful Im rovements in a Pump- Base, of whichthe fdllowing is a specification. The object of our invention as been toprovide a. pumping apga'ratus, consisting of'a motor, a pump, and a ase,which is adapted for readilychanging the ump toIa greater or less numberof stages with to such ends our invention co'nslsts 'in the pumpingapparatus-hereinafter specified.

2111 the accompan top plan view, and an end elevation of an apparatusembodying our invention.

That embodiment of our invention which is illustrated in the drawingscomprises a motor 1 and apump 2, supported by a base 3.

The pump com rlses a'suction-head 4, hav-' mg aleg 5, an a delivery-head6,. havin a leg 7 the suction-head and delive -head eing'united by asection8, which,w1th the two heads; forms .two chambers in which are-"mounted two im ellers, thusmaking a twostage centrifuga ump. Thesuctionfand delivery heads an their supporting-feet are formed ofseparate castings, so .that a greater or less number of sections 8 maybe the expense of changing from one stage pump to another iscomparatively slight, the only expense being to increase or eerease thenumber of sections 8 and of the impelers.

To enable the pump to be readily changed from a pump of one number ofstages to another, we provide a base which is exceedingly cheap, whilebeing very effective for its pur-,

pose; Our base consists simply of two channel-beams 9 and 1.0, which arestood upon one of the flan es on the foundation for the pure and whicare. secured to the feet 5 and 7 an to.the base of the motor. Eachjoot 5a block 12, having vertical sides 13 and 14,*to

which the channel-beams 9 and 10 are secured,- as by rivets 15, the saidfeet. and base having flanges 16.and 17, which respectively overlie andrest upon the upper flanges of the and 7 and the base 11 of the motorconsists of channel-beams 9 and 10; Bolts 18. pass through the feet- 5and? and'through-the motor-basednside the channel-beams and down intothe foundation, and thus secure the pumpingl apparatus upon thefoundation'. The c rigidl secure the motor and pump to ether, but t eserve to aline the shafts. of the 1110-.- tor van pump, o thattheapparatus is readily assembled. v

annelbeams not. only serve to When it is desired to decrease the numberof stages in the pump, the suction-head is disconnected from thechannel-beams and the desired number of sections 8 is removed from thepump, the suction-head beingmoved up against the remaining section 8 orthe delive -head and being again secured to the channe -be,ams andbolted to the foundation. The channel-beams may, if desired, be outoflto correspond to the new len th of the a paratus, or they. may .berep acecl' by s orter bpam's. When it is desired to increase the numberof stages in the pump, it is only necessary to' I'OVldG longerchannelbeams to correspon to the new ength of the apparatus. -Thechannel-beams beingfobtainable in any desired length, it'is easy toadapt the base to any-number of stages in the ump.

= 0 course other. forms of rolled stock can be used in the place of thechannel-bearns,

' the feet 5 and 7 and the motor-base 11 being correspondingly shaped.

We cla1mv p In a pumping apparatus, the-combination of a'motor, acentrifugal pump, said-pump v spendingly-varying lengthof the com risinga delivery-head having a supportingoot, a suction-head having asupportingfoot, and casing-sections connectin said heads, whereby saidsections may number of stages in the pum and a pump base adapted toaccommo ate the correagparatus,

said base consisting of parallel earns to 10 which said motor and thefeet of said pump- 4 he increased or decreased in number to vary theheads can be secured at any required point and yet be in line With'eachother. 7
